| titleOfInvention | Improvements relating to the production of sulphonic acids |
| abstract | Alkane sulphonic acids are prepared by irradiating a paraffin with actinic light or ionizing radiation in the presence of sulphur dioxide, oxygen and between 0.01 and 10% by wt., based on the paraffin, of a monocarboxylic acid free from acetylenic or ethylenic unsaturation and having at least two carbon atoms in the molecule, and in the absence of added peracids. The irradiation may be effected with U.V. or visible light or with ionizing radiation, e.g. that from a cobalt-60 source, and water may be present in the reaction mixture. Suitable monocarboxylic acids include the straight-chain saturated aliphatic acids containing C2- 10 per molecule and the branched-chain aliphatic acids containing C6- 9 per molecule. Aromatic acids may also be used and, if water is present, open chain carboxylic acids containing more than 11 carbon atoms may be employed. The paraffinic starting material is preferably an open-chain paraffin of at least C6 but cyclic paraffins such as cyclohexane, methyl-cyclopentane and methylcyclohexane may also be used. |
